Porsche has revealed its all new 911 (known as 991 internally), and will make its public debut at Frankfurt’s Motor Show in mid-September. If it weren’t for the much thinner looking rear lights, you would be forgiven for thinking that the new 911 isn’t new at all. Luckily mechanical changes aren’t as minimal as the styling. At launch the Carrera will have a 3.4-litre flat-six engine producing 350hp, while the Carrera S will have a 3.8-litre engine with 400hp. The new 911 will have a seven-speed manual transmission – the first of any road car – as well as Porsche’s seven-speed dual-clutch PDK transmission. Acceleration times for PDK equipped cars from 0-62mph are 4.1 seconds for the Carrera S, and 4.4 seconds for the Carrera.Top speed for the Carrera S is 188mph (300.8km/h) and 179 mph (286.4km/h) for the Carrera.

Official details of the long-awaited open-top version of Ferrari’s 458 Italia have been revealed – and it’s called (no prizes for guessing) the 458 Spider.

Ferrari will show the car to the public at the Frankfurt Motor Show in September, and against all expectations, this car will feature a folding metal-top rather the more traditional soft-top. The car has a dry weight of 1,450kg (3153 lbs), and a weight distribution of 42:58 front to rear.

The folding top is made entirely of aluminium, which Ferrari claims weighs 25kg less than a normal soft top, and deploys in 14 seconds.

Under the hood, you will find a non-turbo version of the 5.5-litre V8 engine found in the CLS, E, S, and CL AMGs. Despite being naturally aspirated, the engine still produces a healthy 422 hp and 540 Nm (398 lb ft) of torque.

The engine is connected to a seven-speed Sportshift Plus 7G-Tronic automatic transmission, sending power to the rear wheels. Acceleration from 0-62mph will take 4.6 seconds, while top speed is still electronically limited to 250km/h (155mph).

Ford has revealed the latest in its pickup truck range, a limited edition special for both Harley Davidson and truck fans - the 2012 Harley Davidson F-150.

The new truck comes with new characteristics that include; snakeskin leather accents for the interior; and unique colours and graphics for the exterior. The Harley Davidson F-150 will come with 22-inch machined-aluminium wheels with painted accents, while colour choices will be either White Platinum Tri-coat, or Tuxedo Black.

Ford’s collaboration with Harley Davidson on their trucks started in 1999, and have worked on their bigger F-250, F-350, and F-450 trucks as well. In total, more than 70,000 Harley Davidson F-trucks have been sold.

“All versions of the Harley trucks have been sell out successes,” a Ford spokesperson said. “Most buyers own a Harley motorcycle – who are looking for exclusivity in a powerful, well-equipped truck,” he said.
